It is clear on the holotype figures of both R. haqii and R minutula species (dimension around 4 µm and almoust the same number of elements) that R. haqii has smaller opening (around 1 µm) than minutula (around 2 µm) . Your figures of birefringence and last SEM here mostly are not presented by typical figures of haqii origin. Could you please give us (Paratethian workers who are not dealing with younger sediments) more information why you put this species in hagii?

Reticulofenestra taxonomy is, of course, problematic and difficult to standardise. My approach in the Neogene is to use coccolith size and shape but not central area opening size. Hence for me all the illustrated forms fall in R. haqii.
